GeForce GTX 950 vs Radeon HD 6750

Intro

Compare all that to the Radeon HD 6750, which has core speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 720 SPUs along with 36 TAUs and 16 Rasterization Operator Units.

GeForce GTX 950		90 Watts
	Difference: 4 Watts (5%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950 is 65% faster than the Radeon HD 6750 in general, due to its greater data rate. (explain)

GeForce GTX 950		105728 MB/sec
Radeon HD 6750		64000 MB/sec
	Difference: 41728 (65%)

Texel Rate

The GeForce GTX 950 will be a lot (about 88%) better at anisotropic filtering than the Radeon HD 6750. (explain)

GeForce GTX 950		49152 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 23052 (88%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 950 is superior to the Radeon HD 6750, and very much so. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 21168 (182%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
